Abstract

The utility model discloses a new well lid and a well base, which comprises a well lid and a well base installed on the well lid. Wherein, the well lid and the well base are provided with composite materials and provided with a glass fiber cloth layer and a bamboo sheet reinforced bar. The utility model is light in integral weight and the intensity is 2 times that of the cement well lid intensity, which does not adopt metal materials integrally and is suitable for the inspection well pipeline and the telecom conduit. The utility model is an ideal inspection well lid and well base.

Description

A kind of new pattern manhole cover, seat

Technical field

The utility model relates to tap water, communications optical cable pipeline manhole lid, seat, is a kind of new pattern manhole cover, seat specifically.

Background technology

Traditional Cover of inspection well, well seat are to adopt cast iron to make, and because of losing damage easily, on existing a lot of roads nonmetallic cement well lid have been installed all.Reduced so to a great extent and lost damage.But the well lid that cement material is made is poor because of its corrosion resistance, plaque occurs on its surface in the course of time, and its result has reduced intensity, be full of cracks can take place finally cause fragmentation.In addition, when making cement well lid, need to add reinforcing bar as supporter, to have weight big for the cement composition in addition, and influence is promoted the use of.In addition, although well lid is the cement structures body, the well seat remains metal material, also has problem of ultra-high price on the whole.For this reason, effectively seek a kind of new pattern manhole cover that should not have the applied metal material in light weight, again and avoid losing damage, seat has become the problem that presses for solution at present.

The utility model content

The purpose of this utility model is for addressing the above problem, and a kind of damage problem of losing that do not exist is provided, and can satisfy a kind of new pattern manhole cover, the seat of working strength requirement again.

For achieving the above object, technical solution of the present utility model is finished like this.A kind of new pattern manhole cover, seat comprise well lid and the well seat that is installed on it, and wherein said well lid and well seat have a composite bodies, are respectively equipped with glass fiber layer of cloth and bamboo chip reinforcing rib in it.

In above-mentioned, the composite bodies of indication is that magnesia, magnesium chloride, stone, the sandstone material of selecting for use mixes in proportion.Have in light weightly, smooth surface such as porcelain can reduce the corrosion of soda acid.

In this was novel, the bamboo chip reinforcing rib of establishing in the described well lid was to be " well ", the setting of " water chestnut " shape; Or be the spider reticulation setting.Can effectively increase the intensity and the elasticity of composite bodies like this.

In this was novel, the bamboo chip reinforcing rib of establishing in the described well seat was the annular solid that is bending.Can strengthen the intensity at well seat edge like this.

This novel good effect that has is: the composite material that has certain intensity because of employing, and the glass fiber layer of cloth and the bamboo chip reinforcing rib that are provided with respectively of its inside guarantees the intensity of well lid, well seat and the aggressivity of acid and alkali-resistance effectively in addition; Also have lightweight characteristics simultaneously, but its intensity 2 times of cement well lid intensity really, and long service life; Most importantly the integral body of this structure is not used metal material.

Description of drawings

Fig. 1 is this novel structural representation.

Fig. 2 is another embodiment of Fig. 1 well lid.

The specific embodiment

Below in conjunction with accompanying drawing embodiment, the utility model will be further described.The accompanying drawing of giving only is to be used for reference and explanation usefulness, is not to be used to limit the utility model scope.

By a kind of new pattern manhole cover, seat shown in Figure 1.Comprise well lid 1 and well seat 5.Described well lid 1 is to adopt composite bodies 4, and portion is provided with glass fiber layer of cloth 2 and 3 compression moldings of bamboo chip reinforcing rib respectively within it.Wherein the setting of this bamboo chip reinforcing rib 3 is to adopt " well " shape to distribute to be provided with.Glass fiber layer of cloth 2 related in above-mentioned is provided with one deck at least, and it is provided with the position is between surface layer and bamboo chip reinforcing rib 3; If should be distributed in the both sides of bamboo chip reinforcing rib 3 when adopting two-sided layer gets final product.

In above-mentioned, this bamboo chip reinforcing rib 3 is except that " well " shape, and also can distribute is " water chestnut " shape and all can.Main purposes is as requested chosen.

In above-mentioned, the selected composite bodies of well lid is meant that raw materials such as adopting magnesia, magnesium chloride, stone, sandstone mixes, through compression molding.Therefore this composite bodies has improved 2 times than cement well lid intensity

Above-mentioned well lid 1 is matching used with it to be a well seat 5.This well seat 5 is annular solids that have the convex edge, adopts composite bodies 8 equally, and portion is provided with the bamboo chip reinforcing rib 7 of glass fiber layer of cloth 6 and setting respectively within it.Because of this well seat 5 is annular solids that have the convex edge, set bamboo chip reinforcing rib 7 is to be the bending distribution to be provided with in it.It is provided with density gaps, should select according to the whole wall thickness of well seat 5.For being provided with of glass fiber layer of cloth 6 one deck can be set at least equally, it is provided with the position is between surface layer and bamboo chip reinforcing rib 7; If when adopting two-sided layer, the both sides that should be distributed in bamboo chip reinforcing rib 7 get final product.

Fig. 2 has provided another embodiment of well lid.It is on the basis that Fig. 1 bamboo chip reinforcing rib is provided with, and has done corresponding variation, and promptly the well lid 1 inner bamboo chip reinforcing rib 3 that is provided with is to be the spider reticulation setting.Can increase the elasticity of well lid integral body like this.After well lid is subjected to heavily loaded pressure, can restore to the original state rapidly, can eliminate the body formed well lid of composite material, well seat generation phenomenon of rupture.

Claims

1, a kind of new pattern manhole cover, seat comprise well lid and the well seat that is installed on it, and wherein said well lid (1) and well seat (5) have a composite bodies (4,8), are respectively equipped with glass fiber layer of cloth (2,6) and bamboo chip reinforcing rib (3,7) in it.

2, by the described a kind of new pattern manhole cover of claim 1, seat, it is characterized in that the bamboo chip reinforcing rib (3) established in the described well lid (1), be to be " well ", the setting of " water chestnut " shape; Or be the spider reticulation setting.

3, by the described a kind of new pattern manhole cover of claim 1, seat, it is characterized in that the bamboo chip reinforcing rib (7) established in the described well seat (5), be the annular solid that is bending.
